The expected high chemical and thermal stability of inorganic membranes compared to polymer membranes has resulted in a growing research activity with the aim of replacing these membranes with inorganic ones. Silica and methylated silica membranes do not meet these criteria. The application window of state-of-the-art Me-SiO2 membranes for use in dehydration processes is limited to only 95┬║C. Recently, the preparation of microporous titania or zirconia membranes has been published. The selectivity of these membranes in pervaporation is too low at this moment.
